Spark plug not threading we did a header install and getting close to finish when the driver side last plug didn't wanna go in. tried time and time again and it won't tighten down. my question is do i have to pull the head or is there another way to rethread the hole?
thanks in advance for any help.

Try using a spark plug thread cleaner from auto zone first, and if that doesn't work then you may have to pull the head and send it to a machine shop to have it repaired.

I would avoid using antisieze if possible, it causes you to misthread the plug holes without knowing it. Run the thread cleaner in the hole a couple of times and make sure that all of the gunk it is out of it and use a new spark plug. This will ensure you don't misthread again.
If that doesn't work then pull the head. Don't dare try to repair it while it still on the car, the flakes will ruin your cylinder walls.

Are you saying that antiseize makes you crossthread bolts, sparkplugs etc??? If so you are 110% WRONG. How is that gonna happen? It actually makes them start and thread in easier, you can do it by hand which REDUCES the chance of damaging the threads. If what your saying is true, that would mean that antiseize makes the threads jump outta line.....uh, not happening. I am a machinist, and whether you are just screwing a bolt or whatever in, or actually tappin a hole, cutting threads, some type of lubricant is ALWAYS better.....

Once I cleaned the plug hole and tried it wiyhout the anti-sieze I didn't have any problems with it anymore. I think antisieze is good product, i just don't like using it on aluminum heads.
Antiseize is especially good when used on aluminum material that has steel or other materials in them, it keeps them from possibly trashing the part when disassembling them later.
I have found it extremely easier to thread in header bolts and sparkplugs when using antiseize. And it makes removing them the next time sooo much easier.
I am NOT trying to be a dick or argue, just to help out the poster and understand someone elses different outlook on this topic

I am assuming that you can't even get the spark plug in, not that it wont tighten down, or am I wrong?
Happened to me on the #7 cyl. Took a tap and GENTLY threaded it in and out of the sparkplug hole a couple times, then I used a thread cleaner to clean the threads.... spark plug went in fine after that.

I like anti-seize on my plugs. For the love of god, so this stops happening to people, screw the plug in by hand first. And i don't mean even with just the socket on. You get much better feel with just the plug in your hand. Also, to get the plug started (or any other threaded item) it helps to turn them counter-clockwise for a couple of turns, so you get some feel of the angle it's at! Good luck!
